emission spectroscopy; emission spectrography
Analytical technique that measures light emitted by excited atoms or molecules to determine elemental composition. Used in chemistry, physics, and materials science.
Emission spectroscopy is often used for the analysis of metallic elements.
In this research, the composition of the sample was investigated using emission spectroscopy.
分光法 is the general term for spectroscopy, while 発光分光法 specifically refers to emission-based methods.
吸光分光法 (absorption spectroscopy) measures light absorbed by a sample, in contrast to 発光分光法 which measures emitted light.
plasma emission spectrography
glow discharge optical emission spectrometry
Compound of 発光 (emission of light) + 分光 (spectroscopy) + 法 (method). A straightforward technical term with no obscure historical derivation.
